IMPROVEMENT IN MACHINES FOR CLEANING COTTON.

The Schedule referred to-in these Letters Patent and making part o! the same. M

shaft, and have their forward or acting edges chamfered off, so as to resemble the helical surface of a screw, for the purpose of facilitating the cleansing and loosening of thelocks of cotton. Said arms or beaters e are twistedor so formed as, by the rotation of the shaft, to incline the cotton toward the discharge ilue a', and thus in timeinsure the ejectment ot' the same after traversing the length of the cylinder. y

While the cotton is being carried round by the said rms e, it is also whipped against the aforesaid ribs f of the revolving sieve B,'for the purpose of further assisting the opening and cleansing-operation.

A pulley, c, is fitted upon the shaft C, for reception of a driving-belt, and hy which means a rapid motion is given to said shaft, while a retarded motionis transmitted therefrom, through the medium of a countersliaft and pulleys D, to a pulley, b, connected, by means of a sleeve, i1', with the revolving sieve B, so that by a rapid beating movementofthe radial arms, the dirt and dust are separated from the cotton, and, by a slow turning of the cylindrical sieve, the said dirt and dust, thus beaten from the cotton, and set- To all whom tt may concern Be it known that I, LEWIS T. CLEMENT, of Smyrna, in the county of Rutherford, and State of Tennessee, have invented a new and improved Cotton- Cleaner; and I do hereby declare that the fo'llowing is a full, clear, and exact description of the same, reference being had to the accompanying drawings, rhich form a part of this specification, and in which- Figure 1 represents a longitudinal section of a cotton-cleaner, constructed according to my invention.

`Figure 2 represents a plan view of the same, with the'lop removed; and

Figure 3,.a transverse section of the same.

Similar letters of reference indicate corresponding `parts in the several figures.

The object of this invention is to provide for the more effectual and convenient cleansing of cotton of dirt and dust, while it is yet in the seed; and

The invention( consists in a machine for this purpose, of novel construction,whereby the desired object niay be attained.

Referring to the accompanying drawings- A is a i'ame, of rectangular form, and provided at the upper side of one end with an upwardly-turned inlet or feed-passage, c, for admission of the cotton, and at the lower side of the opposite end with a downwardly-turned outlet-passage, or discharge-due, a', through which the whipped and cleansed cotton is ejected.

B is a cylindrical revolving open-ended sieve, ar-

and its accumulation thereat prevented.

E is a perforated lue, through which the lighter or finer particles of dust are blown hy the current of air produced by the rapid motion of the arms.

Ihe cotton to be cleansed is placed upon the enclosed top G ot the machine, and fed into the feed, opening a,substantially-after the :manner of feeding a giu. 'Ihe cotton, thus?, fed in, finds its wayin at the open .end of the cylinder, and is in time ejected from the discharge-flue a not only in a cleansed condition, but :lso having itslocks loosened or opened, leaving it in better condition for the giu.

What I claim as my invention, and desire to have secured by Letters Patent, is

The combination and arrangement of the feedtable G, feed-aperture a, and discharge-spout a', with the revolving' screen ,and revolving shaft G, pro vided with 'beaters e, substantially as shown and described, for the purpose set forth.

of the seed-cotton.

Said cylindrical sieve is constructed oi' wire gauze, or perforated metal, the meshes or perforations of which are of sutiicient size to permit the free escape of thedust and dirt, but small enough to retain the locks of cotton, and it is provided, upon its inner circumference, with longitudinal ribs f, for a purpose hereinafter explained.

I t is supported upon a rotary shaft, C, which, passing through its axis, turns in journal-boxes situated at the ends of the frame.

Said shaft C is provided with a means of rapid rotation, independently of the revolving cylinder, and it is furnished with radial arms or beaters e, ,which are brought in contact with the cotton during the rotation of the said shaft.

These radial arms e are set spirally around the Witnesses z Taos. l. BAILEY, D. A. WELBoaN.
